Prius (Gen 2) :: 2006 - Warning Lights Appeared On Dash While Sitting At Red Light
Mar 3, 2015
My partner drove the Prius with 54,000 miles to work this morning as he always does. So he is on lunch and sent me a text saying some warning lights appeared on the dash while he was sitting at a red light. I asked if he had any loss of power, if the battery fan was running, he said it drove normally. We bought it last summer with 44,000 miles from a Toyota dealer. They said it had a new inverter pump. It has the original 12v battery however. Though it doesn't act weak at all. No issues this winter at all.
Note, the battery in the photo is at 1 bar. I asked him about it and he said he was driving aggressively to work today, which includes a 2 mile 6% climb he said he made at a high rate of speed... Though after the exit, he has another mile to work.. So the battery should have built itself up before him parking it.

I bought a 2006 Prius with a diagnosed bad battery and tons of warning lights lit on the dash. Toyota had diagnosed a bad hybrid batt and ECU. (I have not replaced the ECU). The car was driving and running fine otherwise.

I actually just bought a used 2004 Prius with 207,011 miles on it from out of state. I had a car shipped to me by a flatbed trailer. I just got the car the last weekend. However, It has a yellow engine light and a big red triangle with an exclamation mark (!) on a dashboard, and a red car with ! on top left of a display screen.
I drove it to a DMV to get it registered and took it to Pep Boys near my place since I have to get it an emission inspection within 10 days of registration anyways.
They ran a diagnostic test and found 2 current error codes (C2310-open/short in battery circuit & C2318-low voltage error) and 1 history code (P0A80-hybrid battery pack needs replaced), so they didn’t perform the inspection; otherwise, it would have a failed record). They told me that the car has had problems before and the problems are about a hybrid transaxle and a hybrid battery pack. They also told me that I need to visit a Toyota dealer to get them fixed in order to pass the inspection, and they warned me that is going to cost me a large four digit probably . So, they suggested me to just trade it in because it is not worth repairing. They also told me that a dealer who sold me the car probably would have done something to the car, that’s why it didn’t illuminate any warning lights before.
I tried to gather as much information as I could, so I asked the shipper if he noticed any warning lights but he didn’t think so; one thing he noticed was the hybrid battery isn’t charged because the engine started every time he moved the car.
I plan to take a car to another auto shop near my place as well in order to have them double check the issues and give me a repair estimate before taking a long trip to Toyota dealer.

Bunch of warning lights appeared and the dealer said it's code P0a80 and they recommend replacing the battery. I'd like to try to fix this myself and would like to hear your thoughts...
Plan is to check the traction battery for corrosion and use a voltmeter to test the cells and replace if needed. Prius 2004, 158,000.

my much adored 2006 prius just got three warning lights as i was driving and slowing down at a light. The big red triangle- "Master Warning", the Brake System Warning, and also, the Hybrid System Warning. It was like warning lights galore... i'll bring it into the dealership first thing tomorrow, but any clue what's going on? I regularly maintain it. The only other thing that ever went wrong with my car is that the touchscreen quit working years ago, and i refused to spend the 3k for them to connect a silly wire. Why my lights went on and is this something serious?

I had just picked my kid up from school, as I turn out of the parking lot my A/C stops blowing cool air, I check the A/C screen and it still says it's set on High with temp at 68. However, it is blowing very low with warm air. Seconds later the dash lights up with numerous warning lights. I'm on the highway and I'm able to gather speed, but each time I do I hear the engine revving like crazy. We only live a few miles from the school so I am able to make it home. Once home, I turn off the car and turn it back on. The only warning lights displayed now are the red triangle and the yellow check engine light. I turn the car off, pop the hood, I check the belt and it was fine. I checked the oil and it seemed fine. I check the coolant overflow and it was empty.

I most recently drove my 2006 Prius around on Saturday Feb. 1, with no problems at all. I went out of town for a couple of days, and returned this afternoon to a car that will not start. I stepped on the brake, pushed Power, and things lit up, the "Ready" light flashed a few times but then went off. Power button light stayed orange.
Several warning lights on dash stayed on (!)/ABS/VSC/traction control, and a message came on the screen saying something about a problem with "P" parking, and that it should be parked level and the parking brake applied. It is sitting level with the parking brake applied already. Also, the door ajar warning light and beep start as soon as you open the car door to get in.
I'm thinking from what I've read that my 12v battery has died/is dying. I'm the original owner, bought car in March 2006, and it has just under 61,000 miles on it.

Today I had the joy of covering 200+ miles on my W12 today. While I was out and about there were 3-4 times I went around a right hand turn somewhat quickly and a "check please lights" warning appeared on the instrument cluster. At the end of the day I inspected the exterior lights with all working or so it seems. I found it odd that this only appeared during sharp turns to the right.

All dash lights and gauges went crazy with a picture of battery in screen and then stopped working for a few miles before working again. I was cruising @65 and this happened and downshifted to 2nd then quickly to 3rd and wouldn't shift again. Stuck in 3rd gear.

I would occasionally have the gauges go crazy and battery light go on but would go away and not have any codes stored. It would only do it towing and always thought it was a ground issue with th

My 2007 Prius with 176k had the warning lights on the dash. I finally got the code read and it is the P0A80 code. The 12 volt battery seems good, it is about a year and a half old or so. That was the only code.

I just bought a 2006 prius. It had 2 bad cells in the battery pack. I replaced the cells and all seems to be well, they all read the same voltage and the car appears to be driving, charging, working.
I still have the red exclamation mark and check engine light. The only code I get says to replace hybrid battery pack.
There are no other specific codes or issues and it runs perfect. Basically I guess what I am asking is how to clear the light or figure out why the light is still on!

There's an ad for a car quite far away from me and one of the photos shows the dash lit up like a Christmas tree. Is this normal during power-up or is it normal when there's something quite wrong?! There is no red triangle of doom shown; I'm unsure if that might be out of shot though. Car is quite high mileage with just over 270,000 km on the clock and is from 2006.

This morning when I started my Prius 3rd Gen 2011, I noticed three yellow lights being on. These were; something similar to handbrake light, ABS light and then the stability control light. All are in yellow. Checked tire pressure and found that one tire was low and filled it. Also, brake fluid was near the low level and I topped it. The lights are still on. I switched on and off several times but the lights are still on.

A yellow key symbol appeared atop the speedometer. I searched the manual and found no reference to this. I assume this to mean the battery may be low in my key fob. Am I correct or does this mean something else?

My Prius yesterday while driving slowly (under 10 mph) all the dash warning lights came on(triangle, cel, trac control, brake). the gas engine started and the message came on that says: "check hybrid system". Today when I went out to check there only two warning lights on (triangle and cel) with the same message displayed. My question is can the vehicle operate without damaging anything if I drive it as is? I have read on several threads that the engine will not start if the hybrid motor(s) are not working. Since my engine starts and runs I have to believe the motor(s) are working.

Warning light appeared, pressure adjusted to 32 psig on all four tires, but light will not go out, even after several miles of driving. Are the tire valve stem Caps special for this feature? I have lost one and replaced it with another type I had.

I have a 2005 Prius with 240,000 miles. About 4 months ago the triangle warning symbol appeared. A friend and I decided to pull the big battery out of the car and find the bad cells. We did that, replace two and the car worked fine for 4 months. The triangle warning has returned. We have done several things but the triangle remains. We pulled the big battery out and checked all of the cells. We replaced one that was probably OK. The latest reading was 8 volts on cells all but one at 7.9. We cleaned all of the bus contacts. We went into the maintenance mode on the MFD and found the aux battery to be 12.6 volts and under load it dropped to 11.8 with the lights on.
The aux battery went up to 14.1 volts with the car on. The inverter cooling fluid has movement and there is a slight humming which I believe to be the inverter pump running. The inverter fluid was topped off. The MFD showed the battery bars start at about three fourths full, drop down to one bar. With the engine running the battery bars climbed to the top purple. The engine turned off and the bars continued to climb to all green. All of this occurred in about 3 minutes while the car was parked. There were codes on the MFD while in maintenance mode. I understand that these codes are for the navigation system and the audio system.

I tried to start car this morning, foot on brake, push power button, all of the warning lights on the dash lit up. shut down, tried again, same thing, third time it went. Same thing after work and then again after an errand. Would like to have some sort of a clue before we take it to the dealer.

I have a 2009 Prius Touring with about 55,000 miles on it. Had it regularly serviced last Thursday at the Toyota dealer/service center, and they said it needed to have the coolant flow control valve replaced due to sticking - so I agreed and they did it under warranty.
On Friday afternoon, I was driving out to the desert and about 50 miles into my trip, the red triangle with exclamation point symbol appeared on my dash, and the word "Problem" beeped on my screen. Then it went off, and then back on a few minutes later. Then it happened again and the high coolant temperature warning light came on the screen...and then went away. I turned off the A/C and opened the hood to check for steam or heat, but there was nothing. Since I was far from my destination, I called the closest Toyota service center and promptly drove there, but the light was off when I arrived. They said they checked everything out and ran the codes, but nothing came up.
When driving home on Sunday, the car did the same thing - Problem Triangle and High Coolant Temperature warning light on and off for varying amounts of time and with no correlation to how fast I was driving or how hard the engine was working. I left the A/C off the entire time.
Today, the car did the same thing after driving for about 10 miles. I brought it back to my regular service center, they ran codes and checked everything out...but they cannot find anything. They said they can't determine anything with the light off, but it doesn't stay on consistently so it's nearly impossible to bring it in with the light on.
